Patent number: 8878135Abstract: A neutron scintillator composite (NSC) is made of a neutron scintillator and a binder. The neutron scintillator of the composite has the formula LiyMgBry+2, where y=2, 4 or 6 and may further comprise cerium as a scintillation activator. The binder of the composite has an index of refraction substantially identical to that of the neutron scintillator. The neutron scintillator and binder are mixed into a solid or semi-solid neutron scintillator composite having sufficient flowability for molding into a shaped article, such as a neutron sensing element of a radiation detector. The neutron scintillator composite collects and channels photons through the material itself and into a photosensing element optically coupled to the composite. Because the indices of refraction for both the neutron scintillator and the binder are substantially identical, scattering at the scintillator-binder interface(s) is minimized, thereby producing transmission efficiencies that approach single crystals.Type: GrantFiled: January 26, 2012Date of Patent: November 4, 2014Assignee: General Electric CompanyInventors: Alok Mani Srivastava, Adrian Ivan

Patent number: 8314399Abstract: A radiation detector includes a neutron sensing element comprising a neutron scintillating composite material that emits a first photon having a first wavelength and an optical waveguide material having a wavelength-shifting dopant dispersed therein that absorbs the first photon emitted by the neutron scintillating composite material and emits a second photon having a second, different wavelength, and a functionalized reflective layer at an interface between the neutron scintillating composite material and the optical waveguide material. The functionalized reflective layer allows the first photon emitted by the neutron scintillating composite material to pass through and into the optical waveguide material, but prevents the second photon emitted by the optical waveguide material from passing through and into the neutron scintillating composite material.Type: GrantFiled: May 17, 2010Date of Patent: November 20, 2012Assignee: General Electric CompanyInventors: Brent Allen Clothier, Adrian Ivan, Chulmin Joo, Daniel Bruno McDevitt
